Admittedly, I am a snob when it comes to my coffee. As far as brewing, each style has it's place and time. I currently have a drip machine, a pour over cone, a french press, and an old percolating kettle. Before being mobile, I had an espresso machine and a few other ways to brew. I have found that it is more important to have fresh beans and the right temperature for your grind (which is also important) than the device for brewing. You can ruin an exceptional coffee by overheating the water and darker roasts like cooler temperatures. The fresher the bean, the less bitter the brew and more intricate notes early and later. Light roasts can really pop when brewed hotter and shorter (205 deg. F for 2 1/2 min.). Dark roasts come into their own around 190 deg. F for 4-5 minutes. These will vary slightly depending on your grind. Coarser grinds take longer and finer hits quicker. Remember that lighter roasts usually have more caffeine and doesn't last well when stored where your darker roasts will be more forgiving. Hope this helps someone out there to try better than store bought from a can.
